Inlet Water Solenoid Valve
1. Test using the controller's indicator lights. Shut unit off by holding the Off button for 3 seconds. Wait
four minutes. Push and release the On button, observe the Water Solenoid indicator light. After the unit
drains the reservoir, the inlet water valve will be powered to refill the reservoir. When it gets power, the
indicator light will be ON. If the water valve does not open to fill the reservoir when its indicator light is
on, do a voltage check. Shut the unit down by holding the Off button in for 3 seconds. Unplug the
harness connection from the inlet water valve. Wait four minutes. Push and release the On button to
restart the machine. After the unit drains the reservoir, the inlet water valve connection should receive
full voltage. If it does, the inlet water valve should be replaced. If there is no voltage, check voltage from
the controller. The inlet water solenoid valve pin is 7.
2. Test using an ohmmeter. Disconnect electrical power. Unplug coil from harness. Measure coil
resistance. If open, replace the inlet water solenoid.
Light is ON when inlet water solenoid
is in operation.
